lui_gough from Gough’s Tech Zone has a new post featuring his interest and progress in improving the reach of his ADS-B reception and plotting ability. His recent project involves using his ADSBpi (Raspberry Pi, RTL-SDR & dump1090), his home PC and another remote PC controlled over the internet. A diagram of this setup can be seen below.

In order to get the most coverage as I can sensibly get, I leveraged my ADSBpi, my main desktop and another machine I have access to which is geographically much closer to the airport via VPN. — lui_gough

This allows him to receive signals from a much larger area than would be possible with a single antenna, single location setup. He does mention a few caveats however, like the increased chance of occasional false decode which can mess with the plotting by visualizing a plane that is unrealistically far away. A big boost to the usability of his project was using Cygwin to compile dump1090 under windows. This allows him to use the dump1090 ADS-B hub features (decoding appears broken under Cygwin compilation) without having to dedicate a machine to linux or use a virtual machine.
